摘　　要：为研究氮、磷、钾肥对水稻(粤优938)产量和经济效益的影响,在通山县大路乡新桥冯村开展了水稻"3414"肥料效应试验研究。结果表明:缺氮相对产量为68.97%,缺磷相对产量为86.03%,缺钾相对产量为82.94%;施纯氮13.45kg/667m^2,纯磷7.03kg/667m^2,纯钾8.71kg/667m^2时能获得最高产量669.07 kg/667m^2,并参照市场价,得出施纯氮12.51kg/667m^2,纯磷5.74kg/667m^2,纯钾7.61kg/667m^2时,能获得最佳产投比。To study the effects of NPK on yield and economic benefits of rice,taking Yueyou 938 as test material,＂3414＂field trial principle was tested on rice in Xingqiaofeng village,Dalu town,Tognshanxian. The results showed that the yield of rice were 68. 97%,86. 03%,82. 94% without N,P2O5,K2O respectively. The rates of N,P2O5,K2O at 13. 45 kg/667 m^2,7. 03 kg/667 m^2,8. 71 kg/667 m^2,the yield was greatest,it＇s 669. 07 kg/667 m^2. it conducted that the ratio of input and output was the best under the rates of N,P2O5,K2O at 12.5 kg/667 m^2,5. 74 kg/667 m^2,7. 61 kg/667 m^2.
